Terraform
Terraform de voiture. Serverspace vous permet de gérer les ressources cloud à l'aide de l'approche Infrastructure as Code. La gestion se fait à l'aide de fichiers de configuration spéciaux dans lesquels vous décrivez l'état souhaité de votre infrastructure.
Pose Terraform
Tout d'abord, installons Terraform dans votre système d'exploitation. Nous recommandons d'utiliser le Terraform manuel du développeur.
Configuration du fournisseur
-
- Créer un API clé pour le projet qui fonctionnera avec Terraform.
- Créez et accédez au répertoire qui sera utilisé pour travailler avec Terraform Fournisseur.
- Créez et ouvrez le fichier de configuration provider.tf.
- Insérez les informations du fournisseur dans le fichier, où
est votre API et enregistrez les modifications : - Ouvrez une invite de commande et accédez au répertoire dans lequel vous avez créé le fichier. Effectuez une initialisation pour vérifier qu'elle est correcte :
terraform initVous verrez le message suivant si l'initialisation est réussie :
Initializing the backend...
Initializing provider plugins...
- Finding itglobalcom/serverspace versions matching "0.2.0"...
- Installing itglobalcom/serverspace v0.2.0...
- Installed itglobalcom/serverspace v0.2.0 (self-signed, key ID 062XXXXXXXXXXXX)Partner and community providers are signed by their developers.
If you'd like to know more about provider signing, you can read about it here: https://www.terraform.io/docs/cli/plugins/signing.htmlTerraform has created a lock file .terraform.lock.hcl to record the provider selections it made above. Include this file in your version control repository so that Terraform can guarantee to make the same selections by default when you run "terraform init" in the future.
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see any changes that are required for your infrastructure. All Terraform commands should now work.
If you ever set or change modules or backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so if necessary.

serverspace = {
source = "itglobalcom/serverspace"

Description de votre infrastructure
Avec Serverspace Terraform Fournisseur, vous pouvez créer une infrastructure avec différentes configurations. Vous trouverez une documentation détaillée dans le Terraform Registre.
Prenons l'exemple de la création d'une infrastructure simple avec deux serveurs connectés via un réseau isolé :
- Serveur à Amsterdam appelé "server-1" avec Ubuntu 20.04 système d'exploitation. Configuration du serveur - 2 Go RAM2 CPUs, 40 Go SSD disque de démarrage, 20 Go supplémentaires SSD lecteur, 50 Mbit/s. SSH connexion au serveur. Stockage de données Redis installé sur le serveur.
- Serveur à Amsterdam appelé "server-2" avec Ubuntu 20.04 système d'exploitation. Configuration du serveur - 8 Go RAM4 CPUs, 40 Go SSD lecteur de démarrage, 70 Mbps.
- Réseau isolé à Amsterdam adressant 192.168.0.0/24
Suivez les étapes ci-dessous pour configurer cette infrastructure :
-
- Créer et ouvrir le fichier ssh_key.tf, qui contiendra la partie publique du ssh clé pour créer le serveur.
- Insérer les informations sur la partie publique du ssh clé dans le fichier ssh_key.tf et enregistrez les modifications, en remplaçant le contenu de la variable public_key par votre valeur :
resource "serverspace_ssh" "terraform" {
name = "terraform-key"
public_key = "ssh-rsa AAAAB3Nza...JUDjlM= root@CentOS.local"
}variable "pvt_key" {
type = string
default = ""
} - Créez et ouvrez le fichier main.tf qui contiendra la description de l'infrastructure.
- Insérez la description de votre infrastructure dans le fichier.
